I am going to be issuing suspensions to 8 hosts with extremely high error counts (over 1000 in their recent history). If you own one of these hosts and are unhappy with the suspension, please message me and we can discuss removing the suspension.

This is a temporary solution until I can implement a more automated suspension system with occasional retesting of hosts to see if they have been fixed.

Any discussion about how to best implement an automated algorithm can go here and I will attempt to keep up.

Jake

Edit:

I added a feature to determine if one of your hosts is suspended at a quick glance. Any of your suspended hosts will show up highlighted in red on the "computers on this account" page in your account information page. These hosts will not show up as red to anyone else and only you will know if you are suspended.

I am going to be reverting the change to use the built in BOINC use reliable hosts option. It seems to be having unintended consequences to the usability of the project for some users.

In the future, Sidd and I will look into manually removing the worst offenders who are sending back erroring workunits.

For anyone effected, I apologize if you haven't been able to crunch for us recently.

We will be temporarily taking the server offline today (3/5) at 1pm to do some further hardware upgrades. This time we are adding a second CPU to the server allow more simultaneous connections.

This maintenance period will likely take longer than the last one as CPUs take longer to install and test.

If you have any questions, please let me know.

Jake

Edit:
Server maintenance is concluded for today. We ended up not being able to complete the upgrade, so we are postponing it for a a week or so.

There will be a scheduled server outage today around 1pm. This should be a brief outage while we install some additional RAM in the server.

Thank you for your understanding.

Jake

The server has been upgraded. Let me know if you see any more database errors or other hiccups here.

In order to use the "Use Reliable Host" feature built into the BOINC server software, we must change our workunit priority to 1 from 0. I am implementing this now and will check in over the weekend to make sure everything is running well.

If you have any questions or see any issues, please let me know.

A new version, v1.68, of nbody has just been released. I have not yet released the mac multi-threaded version (OpenMP). I will release this at a later date.

In this release we have added a new way of constraining the width of the stream. Previously, we were using a measure of the velocity dispersion in each histogram bin. This led us to fit our parameters quite well. Unfortunately, we found that this may not be the best method in the long run. I have added a measure of the beta coordinate dispersion which, from initial findings, will be (hopefully) easier to fit our parameters with.

As always, please let me know if there are issues.

Thank you all for your continuing support,
Sidd

I just tried turning on some options to reduce workunits sent to hosts that return a significant number of errors. If you see any issues, please let me know.

Thank you all for your continued support.

There has been some reports of validation inconclusive issues occurring with the Nbody workunits. It seems to be isolated to the nbody app. I believe this coincided with a database issue on our end. I am working on resolving the issue.

Thank you for you patience and continued support,
Sidd
